Clock Configuration Registers Protection Bit — This bit protects the clock configuration registers from
accidental overwrite (see list of affected registers above).
Writing 0x26 to the CPMUPROT register clears the PROT bit, other write accesses set the PROT bit.
0 Protection of clock configuration registers is disabled.
1 Protection of clock configuration registers is enabled. CPMUSYNR, CPMUREFDIV, CPMUCLKS, CPMUPLL,
